SPECIFICATION forming part of Letters Patent No. 780,211, dated January17, 1905.

Application filed September 2, 1902. Serial No. 122,018.

To @ZZ whom it may concern/.-

Be it known that I, AUGUSTUS CAsNon MAS- sEY, of No. 132 Stimson Block,in the city of Los Angeles, inthe county of Los Angeles and State ot'California, have invented certain new and usefulq Improvements in Axlesfor Railway or other Vehicles, of which the following is a full, clear,and exact description or speciiication, reference being had to theannexed drawings, and to the letters marked thereon.

My invention has for its object to enable the wheels of vehicles used onrailways and other roadways to be rolled upon a curved track withoutstraining the axles torsionally, and besides constructing the axle intwo portions, one fitting into the other at or about the center of theaxle, as set forth in the specifications of my two previous LettersPatent, respectively having the numbers and dates as follows: 662,540,November 27, 1900, and 672,949, April 30, 1901. My invention otherwiseconsists in constructing each halt' of the axle at or near the centerwhere the halves meet with a space between two flanges, one fiange beingon each half of the axle and the space thus formed being' oi suilicientwidth and depth to receive between the ianges a loose ring whose outerdiameter is equal to the diameter of the langes and whose interiordiameter is larger than the diameter of that portion of the axle, whichconsists oi" a cylindrical projection extending from the flange of onehalf oliI the axle to the flange of the other halt' of the axle, so thatan annular space is formed between the interior of the loose ring andthe cylindrical projection on one-half of the axle. In this annularspace antifriction` balls or rollers are carried, and the whole of thesecentral parts, including the iianges, the loose ring, and theantit'rictionrollers, also the adjacent parts oi' the axles, are carriedwithin'a yoke or box which holds the parts together, the entireconstruction or arrangement being such that the parts are held togetherantit'rictionally, so that they can yield rotatively on the occurrenceof any torsional strain produced by any pair or' wheels and axle rollingupon a curved track of which the rail of one track is longer than therail of the other track.

On the annexed drawings, Figure l is an elevation, partly in section,oi. a pair of wheels and a railway-car axle constructed in accordancewith my present invention. Fig. 2 is an elevation of the central partor' the axle, showing the exterior etl the yoke or box containing andholding in operative relationship the yielding' parts thereof. Fig. 3 isa transverse section on the line a e, Fig. 1. Fig. 4c is a transversesection o-n the line Fig. 1.

1n the drawings each halt' oli the axle is marked A and A',respectively. On the half of the axle marked A there is formed thelflange B, and on the other hali` of the axle marked A there is formedthe liange B'. Projecting from the center of the iange B is thecylindrical portion marked (l, Fig. l, which extends across the spacebetween the flanges B and B', so that the outer end of the cylindricalportion C bears against the central portion ci the flange E, and thecentral part otl the axle A/ is formed with a conical nose D,projecting' from its iiange B into a corresponding conical recess in thecylindrical part C of that haltl of the axle marked A. As will be seenby reference to the drawings, an annular space is thus provided betweenthe flanges B B, wherein the loose ring E is placed, and in the annularspace thus formed between the interior or' the loose ring E and. thecylindrical projection C the antifriction balls or rollers F arecontained. The whole of the central parts et' the axle thus constructedare held together by means elI the box or yoke G, which is constructedin two halves, as shown in the drawings, the halves constituting' theyoke being held together by bolts and nuts H.

1n putting the several parts or' this device together they are oiled orgreased, so as to allow the saine to yield rotatively with a miniinunifriction on the arising et a torsional strain, and any oiling device maybe applied to the yoke for passing oil as a lubricant to the interiorparts whenever necessary, such lubricating device, however, forming nopart ot' this invention..

I would have it understood that my invention includes such changes andmodifications in the shape of the device and its parts as may i'allWithin the terms and scope of the following claims.

Having now described the nature ot' my said invention and the bestsystem, mode, or manner I am at present acquainted with for carrying thesame into practical effect, I desire to observe in conclusion that whatI consider to be novel and original and therefore claim as the inventionto be secured to me by Letters Patent, is as follows:

l. The axle-joint wherein each half of the axle is constructed at ornear its center with a iiange of larger diameter than the axle itself,one haltl of the axle having a cylindrical nose projecting' from itscenter toward the other half of the axle thus forming a space betweenthe flanges, the other haltI of the axle having a nose projecting into arecess in the central cylindrical projection of the first-namedhalfaxle, the space between the fianges containing a ring Whose externaldiameter is the same as the external diameter of the flange, and havingantifriction balls or rollers in the annular space formed between theinterior of said ring and the cylindrical projection, the Whole beingcontained or held in operative relationship within the box or yoke,substantially7 as hereinbefore described.

2. The combination of the two half-axles, each half-axle having a flangeat or near its inner end, the cylindrical central projection on onehalf-axle, the ring in the space between the flanges, the antifrictionballs or rollers in the annular space formed by the interior of the ringand the exterior of the cylindrical projection, the conical nose andrecess on each half-axle, respectively, the box or yoke and bolts forholding or containing the whole of the parts in operative relationship,substantially as hereinbei'ore described.

In testimony whereofl I have hereunto set my hand and seal, this 10thday of July, A. D. 1902, in the presence ot' two subscribing Witnesses.
